ABSTRACT
Vascular endothelial growth factor 121 (VEGF(121)) was expressed as inclusion bodies by recombinant Escherichia coli. High concentrations of both biomass (46 g dry cell/L) and VEGF(121) inclusion bodies (4.5 g/L) were obtained by applying a high-cell-density culture. After the inclusion bodies were washed and dissolved, VEGF(121) was refolded at 0.2 mg/ml by ultrafiltration in refolding buffer with a yield of 81%. Renatured VEGF(121) was purified by anion chromatography and Sephacry S-100 chromatography with purity higher than 95% and final purification yield of 31%. The purified VEGF(121) could stimulate the proliferation of human umbilical vein endothelial cells as demonstrated by a biological activity assay.
